Setting up blocked numbers
The telephone system provides you with the option to block dialling of certain
telephone numbers or digit sequences. 20 blocked numbers and 16 (+ fixed
emergency numbers that cannot be deleted) exception numbers are available.
With blocking activated first the dialled number will be verified. In case a
blocked number has been detected the connection will be terminated after the
last digit and you will hear the busy signal. Blocking can only be applied to
external calls. External line access by dialling 0 (94 or 95) is not part of the list
of blocked and exception numbers.
Blocked numbers can be overruled by a list of exception numbers. The
exception numbers have higher priority.
Example:
Blocked number is 0190, exception number is 01901.
Dialling telephone number 01902 456789: This dialling attempt will be
terminated as soon as you dial the digit 2.
Dialling telephone number 01901 456789: This attempt will not be affected.
Activate/deactivate blocked numbers
Blocked numbers can be activated/deactivated individually for each telephone.
Programming can be carried out via telephone 21 according to the table below.
In the factory default settings blocked numbers are deactivated.
